Paper Abstract

The proposed new interfacial spectroscopic method allows to measure the fluorescence emission spectra of the two tryptophans of the Bovine Serum Albumin (BSA) during its adsorption at the air/water and egg-lecithin (egg-PC)/water interfaces, using an UV excimer laser. Surface fluorescence spectroscopy shows changes in the spectroscopic properties of adsorbed BSA, spread BSA and mixed egg-PC/BSA films. These results are related to the surface pressure measurements which characterize the different BSA surface organizations.
